Ibaraki's industries include energy, particularly nuclear energy, production, as well as chemical and precision machining industries. The Hitachi company was founded in the Ibaraki city of the same name.

As of March 2011, the prefecture produced 25% of Japan's bell peppers and Chinese cabbage.[5]

The prefecture is often mispronounced "Ibaragi". However, the correct pronunciation is "Ibaraki". According to the author of "Not Ibaragi, Ibaraki",[6] this is most likely due to a mishearing of the softening of the "k" sound in Ibaraki dialect.
